Synchrophasor systems, like Phasor Measurement Units (PMUs), are a key element of smart grids. They have the capability to measure time-coherent phasors of a grid. The key advantage of PMUs is the fast sampling rate that they provide over traditional Supervisory control and data acquisition (SCADA) systems which can be in the range of 30-120 samples/second. These higher sampling rates come at the cost of higher data quantities. Generating large amounts of data per day poses a challenge in making the most efficient use of information. In this paper, this problem has been addressed utilizing machine learning techniques, Logistic Regression Analysis, on PMU data. Identifying system anomalies in smart power grids is the primary focus of this paper. The standard IEEE 39 Bus system has been modified using the RT-LAB environment to generate faults and to produce synthetic synchrophasor data. Archived/offline mode data from a Phasor data concentrator (PDC) database is being used to train and test the algorithm. Additionally, the algorithm has been tested in real-time using an OPAL-RT digital real-time simulator.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129952812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advancements in solar materials have made possible the ability to apply photovoltaic material on curved surfaces. This non-planar arrangement leads to complications since there is no-longer uniform insolation or cell temperature. Hence, a model is needed to be able to evaluate the performance of the PV system. This paper presents a method to model a non-planar PV surface and calculate the theoretical energy collection potential and power profile. The technique is demonstrated by application to two curved surfaces both having the same two-dimensional projection (footprint). The results suggest that curved surfaces are able to increase the collection ability compared to a flat plate of the equivalent footprint by over 50%. Additionally, the harvest profiles of curved surfaces are found to produce multiple peaks over the day to broaden the generation profile curve by boosting the morning and afternoon shoulders of the generation curve. Since the harvest profile directly correlates to the surface geometry, it stands to reason that curved photovoltaics can be designed geometrically for specific applications like extended energy collection or maximum power output at certain times.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"382 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122304926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper performs different scenario - case study to show how DER could strengthen the grid and help mitigate grid disturbances, as well as function as the grid resource for faster system response and recovery. A simple model built using Matlab/Simulink, highlights the automated control across the system utilizing voltage control. The model consists of a PV system integrated to the grid through a boost converter based Maximum Power Point Tracking (MPPT), and a Battery Energy Storage System (BESS) integrated through a bi-directional DC/DC Converter. Comparison of different converter types is conducted, and calculation of system configuration parameters is done to optimize the model. Different PV outputs influenced by environmental parameters and different load demand are also simulated under both grid-connected and islanded operation mode proving the system is properly designed and configured. Levelized Cost of Electricity (LCOE) and Levelized Cost of Delivery (LCOD) are then estimated on the model, proving the promising future of microgrid implementation based on the current market, especially in rural areas.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133407787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed system interconnects different energy sources (i.e. grid, solar, wind and batteries) in a DC-based core eliminating the necessity of synchronization schemes. If the grid fails, the system acts as an uninterruptible power system proving energy from the other sources without any transfer time. A diode-based OR-gate circuitry is able to self-commutate given the I vs V curve of the solar panel allowing source combination to be transparent to the user. The diode efficiency is estimated and measured reporting close to 94%, which justifies the proposed DC core approach. The system is complemented with converters that, for the case of commercially available devices, produce a measured total efficiency up to 82%. Such performance metric is possible considering a battery system with embedded configuration mechanism that bypasses the batteries when not required. For this work, the battery pack is selected small, so that the system can be kept affordable in terms of price and maintenance. As the backup system is limited, the platform is equipped with a load shedding strategy to provide uninterruptible energy only to predefined essential loads. During normal operation, the proposed system offers economic benefits for users since reduces the power energy required from the grid.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134372457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alternative farming methods such as indoor agriculture are possible solutions, however, current methods utilize a considerable amount of electricity to provide plants with artificial light. Optical fiber daylighting systems (OFDs) offer a way to direct sunlight indoors over long distances and can therefore reduce electricity usage. Currently, the market mostly includes active OFDs that use a motor and sun-tracking mechanism. This can be complicated and expensive to develop and operate. Therefore, our research focuses on developing and optimizing a passive OFD system. Passive OFDs are static structures that use their geometry and the laws of optics to redirect light. Optical simulation software, CAD software, additive manufacturing, and waterjet tools were used to develop an optimal passive OFD prototype for data collection. Vegetative plant growth requires a photosynthetic photon flux density (PPFD) of 250 and higher. Our prototype design provided a photoperiod of 210 minutes at a high (above 250 PPFD) level, 179 minutes at a medium (above 170 and less than 250 PPFD) level, and 175 minutes at a low (below 170 PPFD) level. This research supports the development and implementation of an effective passive OFD system for indoor farming operations at a significantly reduced cost, with increased feasibility in a more environmentally friendly approach.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117140563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
